HUMIDIFIER.

Specification of Letters Patent.

Patented Dec. '2, 1999..

Application filed Marelr22, 1909. Serial No. 485,011.

To all whom it may concern:

Be it known that I, FRANK B. CoMrNs, of Sharon, in the county of Norfolkand State of Massachusetts, have invented certain new and useful:Improvements in Humidifiers, of which the following is a specification,reference being had to the accompanying draws ings, forming partthereof.

This invention has reference .to improvements in humidifiers or airmoistening ma- Oneobject of the invention is to so construct ahumldifier that an extremely large volume of air may be passedtherethrough and completely saturated with moisture without carryingfrom said machine free moisture capable of being condensed into drops inthe atmosphere under normal conditions of use.

Another object of the invention is to so construct a humidifiercomprising duplex air nioistening means that the separate bodies of airmay be brought together and thoroughly mixed and that free moisturetherein may be. condensed and deposited before the humid air passes fromthe machine.

Another object of the invention is'to so construct a duplex airmolstenmgmachine.

that all parts of the same may be readily accessible for cleaningpurposes.

()therfobjects of the invention will appear from the followingdescription.

' The invention consists in certain peculiar features of constructionand combinations of parts and of groups of parts as shall hereinafter bemore fully described and pointed out in the claims.

Machines of the general character referred to herein are designed andintended for use in textile and other manufactories in order to purifythe air and render the same humid to any desirable degree. In ordinaryuse one or more of these humidifying machines is suspended in a room andcurrents of air, carrying impurities and light particles of foreignmatter are induced to flow through the machine or machines where suchair is subjected to thedirect action of moisture by which the air is sosaturated that the particles of foreign matter arowashed therefrom andthe air is rendered humid. After continued usethe impurities andparticles machine, and this is particularly the fact when the machine isadapted to moisten large amounts of air, as in the machine of the classherein specially shown and described.

Figure 1, represents a vertical sectionalview of the improvedhumidifier. Fig. 2, represents a detail view of one of the door hingingand lifting devices. Fig. 3, represents a cross sectional View taken online 33 Fig. 1. F1g. 4:, represents a side elevation of parts of thehumidifier showing details of construction and illustrating the mannerin which the inner casing may be swung out of the outer casing andsustained in position to permit access to the rear portion of said outercasing. Fig. 5, represents a front elevation of the improved humidifierin the closed. position.

Similar numbers of reference designate corresponding parts throughout.

In carrying this invention into practice I provide a hanger having thecross bar 7, on which the bearing for the usual fan 8 may be mounted ifdesired, and from said bar 7 I extend downward the arms 9 and 10 adaptedto carry the weight of the humidifier. Arm 9 has the vertical guides 11-11 in bearings of which is journaled'the rod 12 having the .member 13furnished with the cam edge 14 and having the handle 15. Arm 10 has thehook shaped engaging devices 16 and 17 and the ears 18-18 in which isjournaledthe rod 19 having the member 20 furnished with the cam edge 21and having the lever 22.

The lower ends of the arms 9 and 10 are preferably secured to the dripbasin 23 having any'usual drainage means and furnished with frame 24having the outwardly inclined plates 2525 adapted to collect surplusmoisture from air passing thereover and to guide said moisture towardthe drip basin.

The outer edge of the drip basin QS-is formed by the ring 26 which formsthe lower mem ber of the annular air outlet 27, the upper member of saidoutlet. being formed by the combined segmental and flared members 28 and29 of which the member 28 is secured to the said ring 26 and to thesegmental outer casing member 30 while the member 29 is secured to thesegmental door 31.

, At the inner side of the casing member 30 is mounted the segmentalconcave plate 32 having the bafile plates 33-33, inclined to the radiiand the arms int-34 which latter are secured to said member 30. To thedoor member 31 are secured the arms 35 35 or" the segmental concaveplate 36 which is complen'iental to the plate and has the battle plates3T-87 also inclined to the radii of the circle formed by'said combinedplates. This door member has also the outwardly bent edges 38 and 39,adapted to be engaged by the hook shaped members 16 and 17 of the hangerarm 10, and the rider 40 adapted to ride on the edge 21 of the cam 20when said door is in the-closed position. Said door has also, at theedge nearest the hanger arm 9, the straps 4C1t1 whichare journaled onthe rod 12, and are adapted to be engaged by the arms of the guides11-11, and the rider the door 31 is more particularly described inLetters Patent No. 931,845 granted to me AugustQ i, 1909. I

Pivotally mounted between the hanger arms 9 and 10 is a stren theninframehaving the cross member 43 having the depending inclined arms44.44-'or other suitable suspending means'for the inner casingcomprising the segmental member 45 and its door 46 suitably hingedthereto by. a "hinging and lifting mechanism similar to that. abovedescribed. As a means for sustaining such casing 4546 when swung outwardon the pivots of the cross bar 43, as shown in Fig.

4, I prefer to supply said bar 43' with the depending arms 47- 17 havingat their lower ends the pairs of pivoted links 4=848 which are sustainedby pivots extending-inwardly from the arms 9 and 10. 1

Water under pressure is delivered to the nozzle 49 by any suitable meansand the fan 8 is operated to force air downward. A por tion of said airpassing through the inner casing formed by the gnembers 4:5 and 46 ab-.

sorbs comparativelya large amount of water in the restricted passageformed by said inner casing. A body of air, of greater volume than thatpassing through said inner casing is, at the same time, forced by fan 8downward between'the inner and outer casings and this latter air movesat a speed somewhat greater than the speed of the heavier moistened airpassing through said inner casing. i/Vhen now the large volume ofcomparatively dry air passing downward between the inner and outercasings reaches the deflector plate 32-36 said air is directed inwardand, moving in that direction, is guidedby the plates 33-37 in acentripetal course with reference to the body of humid air issuing fromthe lower end of the inner easing whereby said body of humid air istaken up by the embracing volume of comparatively dry and expansive airand a vortex is created in which the dry air is satu rated with thehumidity of the volume of moistened air. After receiving said moisturethe combined volumes of air pass downward over the edges of the plates32-36 and are directed outward over the central cone of frame Qt passingover the inclined plates 2525, which tend to condense the free moisturein such air, and through the annular opening 27.

When it becomes necessary or desirable to .clean the casings orcylinders, levers 15 and22 are swung outward from the positions shown inFig; 5, as indicated in Figs.

2 andA, and the riders 10 and 42, with the door member 31, will be movedupward by the bearing thereagainst of the cams l3 and 20 until thestraps ll-41 are above the ends of guides l1-ll and the lips 38-39 ofsaid door are disengaged from the. hook shaped members 16l7, the doormember may then, be swung outward as indicated in dotted lines in Fig.3.

. If desired the door member 16 of the innercasing may now be opened onits hinges and such parts. of both casings as are ac cessible may becleaned'but, preferably, the inner casing may now be'swung outward byhand, on the pivots of the cross bar 43, through the opening between theends of the casing member 30 approximately to the p0 sition shown inFig. 4 and may be sustained in such position by the pivoted arms l818during the cleaning operation on both casings, it being obvious thatsaid inner cylinder may be cleaned, in such position, withoutopening'its door member.

" It is not my desire to limit my invention to the specific hingingmeans for the door sections and it is evident that the inner cas-' ingmay be movably mounted with respect to the outer casing in various wayswithout departing from the spirit of this invention. When pivotallymounted the inner casing need not swing outward to the extent hereinshown and when swung outward may be supported in any desired manner.

Having thus described my invention I claim as new and desire to secureby Letters Patent.

1. A humidifier comprising two air passages one embraced by the other,the outer of said air passages having a door opening larger than thediameter of said inner airpassage. r

2. A lnnnidifier comprising two cylinders, one within the other, ofwhich the outer has a door opening, and a mounting for said innercylinder on which. said inner cylinder may more through the door openingof the outer cylinder.
